Answer: This is blossom end rot, usually it is caused by uneven soil moisture levels. Try to water as needed to keep the soil evenly moist like a wrung out sponge, not sopping wet/saturated but never dried out. To know if you need to water, use your finger to check the soil, if it is still damp do not water yet. When you do water, water slowly and thoroughly so it soaks down deep into the soil. After watering, wait a few hours and then dig down to see how far it went; sometimes it can be surprising. It is better to water deeply but less often than to sprinkle lightly every day. Using ample organic matter when you prepare the soil prior to planting can help it hold moisture longer, and using an organic mulch can also help keep the soil more evenly moist.
